Abstract
A fixed pad thrust bearing for a turbomachine comprises a ring of sector-shaped pads separated by grooves and facing a thrust collar integral with the rotor of the turbomachine within a thrust bearing cage integral with the rotor. The ring bears on a deformable ring. Each pad is fed with oil via a space formed in the wall of the cage and facing an orifice in a bore in the pad. A front surface of each pad facing the collar is inclined relative to the rear surface of the ring. Each pad is further formed with a groove communicating with the aforementioned bore but not reaching as far as the inner and outer edges of the pad, being disposed adjacent the leading edge of the pad. The oil is recovered centrifugally from the outer edge of the collar. In this way, virtually all the power consumed by the oil goes towards providing the hydrodynamic supporting force, minimizing the shearing losses between the fixed and moving parts within the thrust bearing cage.
